Learn about the causes, symptoms, diagnosis, and treatment of cat scratching

What is cat scratch disease?

Cat scratch sickness is bacterial contamination spread by bug tainted felines when a tainted feline licks, nibbles, or scratches an open injury on somebody adequately hard to tear the surface of the skin. 3 to 14 days after the skin ruptures, a minor infection occurs at the site of the scratch or bite.

The affected area may appear swollen and red, with circular and bulging wounds, and possibly the presence of pus. The site of infection can feel warm and sore, and a person with cat scratch disease may develop a fever, headache, poor appetite, and fatigue. Then, the lymph nodes closest to the site of the injury can become swollen and tender with or without pressure.

What is cat scratch disease?

Wash the nibble or scratch altogether with a cleanser and running water. Do not allow cats to lick your wounds. Call your doctor if you develop any symptoms of cat scratch disease or infection. This scratch is caused by a bacterium called Bartonella henselae. 40% of cats carry Bartonella bacteria in their lives, although most infected cats show no sign of disease. Young kittens less than a year old are more likely to be infected with the bacteria and pass it on to humans. Also, kittens are more likely to bite and scratch others when they are playing and learning to hunt.

How do cats and humans get infected?

Cats become infected with Bartonella henselae bacteria when exposed to flea bites and dirt, and it enters their wounds. When a cat scratches and bites fleas, they pick up dirt under their claws and between their fangs. A cat can also become infected when it fights with other infected cats.

Germs are transmitted to humans when a cat scratches or bites someone hard enough to rip the skin. Germs can also spread when an infected cat licks wounds.

Serious but rare complications


Although complications from cat scratch disease are rare, they are serious. Cat scratch disease can infect the brain, eyes, heart, and other internal organs. These are uncommon side effects, which may require serious treatment, and are bound to show up in kids under 5 years old and patients with traded-off safe frameworks.


Most cats that carry Bartonella henselae bacteria show no signs of disease, but it is rare for the disease to cause inflammation in the heart, making cats very sick with trouble breathing. Bartonella henselae bacteria may appear in the mouth, urinary tract, or eyes. Your vet may find that some of your cat’s internal organs have become infected.
